Welcome to our comprehensive collection of traffic sign blanks, the essential foundation for all road signs and traffic control devices. These high-quality aluminum and steel blanks serve as the perfect canvas for reflective sheeting and traffic messaging, ensuring visibility, durability, and compliance with transportation standards. Whether you're a municipality, contractor, or private business, our selection of sign blanks provides the perfect starting point for creating effective traffic signage.

What Are Traffic Sign Blanks?

Traffic sign blanks are the unprinted metal substrates that form the structural base of road signs. These pre-cut metal sheets come in various shapes, sizes, and materials, ready to receive reflective sheeting and printed graphics. The quality of these blanks directly impacts the longevity, visibility, and performance of the finished traffic signs.

Materials Used in Our Sign Blanks

We offer sign blanks manufactured from premium materials to ensure maximum durability and performance in all environmental conditions:

Aluminum Sign Blanks

Our most popular option, aluminum sign blanks offer an excellent balance of lightweight construction and weather resistance. These blanks won't rust and can withstand years of outdoor exposure while maintaining structural integrity.

Steel Sign Blanks

For applications requiring additional strength and rigidity, our steel sign blanks provide superior durability. These galvanized steel blanks feature anti-corrosion coatings to prevent rust and deterioration.

Aluminum Composite Material (ACM)

These modern sign blanks feature a polyethylene core sandwiched between two thin aluminum sheets, offering excellent flatness, weight reduction, and vibration dampening properties.

Standard Shapes and Sizes

Our inventory includes all standard traffic sign blank shapes conforming to MUTCD (Manual on Uniform Traffic Control Devices) specifications:

• Circular blanks for regulatory signs
• Octagonal blanks for stop signs
• Diamond blanks for warning signs
